A) \[\frac{v}{2a}\]
B) \[\frac{4v}{3a}\]
C) \[\frac{v}{3a}\]
D) \[\frac{3v}{4a}\]
Correct Answer: D
Solution :
Angular momentum about A will be conserved, i.e., \[{{L}_{i}}={{L}_{f}}\] \[mva=I\omega \]or \[mva=\frac{m{{(2a)}^{2}}}{3}\omega \]\[\therefore \]\[\omega =\frac{3v}{4a}\] Hence, the correction option is [d].You need to login to perform this action.
